The production of alkali-activated binders uses less energy and produces less carbon dioxide than conventional Portland cement (PC). These binders also offer flexibility in materials sourcing and can also give better durability to sulfates and acid than PC.
This Digest summarises the state of the art in this emerging area of construction technology. It draws on BRE’s expertise in the area and provides an introduction to these new binders, their use in concrete production and their performance and durability. It is aimed at specifiers of concrete products, concrete product producers and those with an interest in the applications and materials performance of low-carbon concrete products.
